    • The instant invention pertains to a multi-layer tamper proof electronic coating wherein the first layer is a protecting layer produced from preceramic silicon containing material and at least one filler. The second layer is a resin sealer coat produced from a sealer resin selected from the group consisting of colloidal inorganic-based siloxane resins, benzocyclobutene based resins, polyimide polymers, siloxane polyimides and parylenes. An optional third layer is a cap coating layer selected from SiO.sub.2 coating, SiO.sub.2 /ceramic oxide coating, silicon containing coatings, silicon carbon containing coatings, silicon nitrogen containing coatings, silicon oxygen nitrogen coatings, silicon nitrogen carbon containing coatings and/or diamond like coatings. An optional fourth layer is a resin overcoat produced from an overcoat resin selected from the group consisting of colloidal inorganic-based siloxane resins, benzocyclobutene based resins, polyimide polymers, siloxane polyimides, parylenes, photoresist polymers, siloxane room temperature vulcanizable compositions, or other organic polymer. The use of the multi-layer coating on the electronic device results in an electronic device that is resistant to analytical techniques such as ozone, UV-ozone, gaseous free radicals and ions, vapor or liquid borne reactive species, plasma, abrasion, radiation, light, wet etching and others; moisture; chemicals and other environmental contaminants; shock and erosion, delamination and/or separation.
